Sagot :
In the first circle, 12 seeds can be planted. And to plant 20 seeds, the diameter must be 12.74ft.
What is the maximum number of seeds that can be planted?
We know that the flower seeds will be planted on a circle of diameter of 8ft. The circumference of said circle will be:
C = pi*D = 3.14*8ft = 25.12ft
And each seed is 2ft apart from seeds on the other side, so the maximum number of seeds that can be planted is:
N = 25.12ft/2ft = 12.56
Which must be rounded to 12, as we can't plant a 0.56 of a seed.
Now, we need to find the diameter of a circle such that 20 seeds can be planted there.
To plant 20 seeds, the circumference needed is:
20*2ft = 40ft
Then, for a circle of diameter D, we need that:
3.14*D = 40ft
D = 40ft/3.14 = 12.74ft
The diameter of the circle must be 12.74ft
